I do have a server with 2 CPUs (22 Cores each plus HT). I created a KVM Guest with 64 allocated cores. When I run a compilation task the virtual machine shows all 64 cores at 100% (at moderate Disk I/O and memory usage) but on the physical machine the guest only uses 14 cores at 100% instead of all the 88 cores randomly (or 64 dedicated cores at 100%). Even if I spawn more compilation tasks this doesn't change. Is there any parameter or setting I have to change to actually use all the computing power that is available?
